OILER.

Specification of Letters Patent. Patented S t. 25 1917 Application filed December 26, 1916. Serial No. 138,914.

To all whom it may concern:

Be it known that I, GEORGE O. GILBERT, a citizen of the United States, residing at Montrose, in the county of Montrose and State of Colorado, have invented certain new and useful Improvements inOilers, of which the following is a specification, reference being had to theaccompanying drawings. I

This invention relates to certain improvements in oilers and it is an object of the invention to provide a device of this general character which, at all times, is non-leakable and which includes a reservoir that will retain oil therein without spilling or leaking when the device is in use as well as when the device. is not in use. a a

The invention also has for an object to provide a novel and improved oiler including a gun adapted to be sheathed, when not in use, within a reservoir containing a sup ply of oil together with means whereby the gun is caused to automatically operate to charge the same before the gun is removed from within the reservoir. I

The invention consists in the details of construction and in the combination and ar rangement of the several parts of'my improved oiler whereby certain important advantage are attained and the device is rendered simpler, less expensive and otherwise more convenientand advantageous for use,

all as will be hereinafter more fully setforth.

The novel features of the inventlon Wlll hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same'with reference to the accompanying drawings, wherein is disclosed a longitudinal sectional view taken through an oiler constructed in accordance with an embodiment of my invention.

As disclosed in the accompanying drawings, C denotes a cylindrical container of predetermined dimensions and having one end closed by the substantially cone-shaped head 1, the apex of which being disposed outwardly and it is also to be noted that said head 1 is positioned inwardly of the adjacent end of the container so that the apex of the head 1 will be substantially flush with the adjacent end of said container C so that if desired said container may be conveniently rested upon said end.

The opposite end of the container is provided with a removable head or cap 2 which affords a convenient means for filling the container O with a supply of oil.

At substantially its axial center the removable head of cap 2 is provided with an opening 3 defined by an outstanding annular flange or sleeve 4 provided with external threads, and extending inwardly from the removable head or cap 2 and in continuation of the annular flange or sleeve 4 is a tube 5. The tube 5 is of such a length as, when the removable head'or cap 2 is in applied position upon the container C, to terminate in close proximity to the axial center or apex of the head 1, and the inner end portion of said tube 5 is tapered, as at 6, and is provided in its inner end with the restricted opening 7. I

G denotes an oil gun readily insertible within the tube 5 through the entrance afforded by the annular flange or sleeve 4 and, as herein embodied, said gun G includes a barrel 8 provided with an elongated tap ering discharge nozzle 9 at one end thereof and which nozzle 9 is adapted to extend through the restricted opening 7 in the in: nor end of the tube 5, the peripheryof said nozzle 9 preferably having frictional contact with the wall of said opening.

Mounted for rectilinear movement within the barrel 8 is the piston 10 operatively engaged with the rod 11, said rod 11 extending exteriorly of the barrel 8 through the end thereof remote from the nozzle 9. The outer end portion of the rod 11 is provided with the cap 12 adapted to be engaged with the threaded periphery of the sleeve or annular flange 4, whereby it will be perceived that the gun G is effectively held within the tube 5 and the piston 10 maintained at the limit of its movement inwardly of the barrel 8.

The rod .11 is of a length less than the length of the barrel 8 so that the expansible member 14 may be readily interposed between the piston 10 and the adjacent end portion of the barrel 8, said expansible member being herein disclosed as a conventional coil spring bearing against the inner face of the piston and an annular shoulder 15 afi'orded by the nozzle 9.

It will be at once self-evident that with the gun Gr sheathed and locked within the tube 5, the expansible member 14 will be compressed and that when the cap 1:2 is disengaged from thea'nnular flange or sleeve to facilitatethe drawingv of the oil Within the barrel 8 when the piston 10 is forced outwardly under the influence of the expansible memberlt as hereinbe-fore set forth.

if preferred the annular flange or sleeve 4: may be surrounded by a gasket 16 with which the -cap 12 contacts to effectively preventany possible leakage of oil and it will also be understood that if desired a gasket 17 maybeinterposed between the container C and the removable head or cap 2.

I From the foregoing description, it is thought to be obvious that an oiler, constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is (particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification 'w-ithout materiab departure from the principles and spirit thereof and for this 'reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying iout my invention in practice, except as hereinafter claimed.

vopl es'of this patent may be obtained for-l barrel, a piston and an operating rod for the piston, said barrel being insertible within the tube and provided with a tapering nozzle adapted to extend through the restricted opening of the tube, said nozzle when extended through the restricted opening of the tube terminating in close proximity to but spaced from the closed end of thecontainer, said closed end being substantially coneshaped with the apexthe-reof dis-,.

posed outwardly, a cap carried by the outer end portion of the rod and engageable with the outstanding flange of 'the-iirstonamed cap for holding the gun within the tube and maintaining the piston of the gun at the limit of its inward movement, said rod being of a length; less than the length of the barrel, the inner end portion of the barrel being provided with an inwardly directed shoulden, and an-expans'ible member positioned within the barrel intermediate the piston and the shouide'r of the bar-rel for constantly urging-said piston outwardly.

In testimony whereof I hereunto signature in the presence of two witnesses. GEORGE O. GILBERT.
